Screw:

• M3x5mm (x4) : attach motor to casing - no nut needed
• M3x12mm (x4) : attach the screw to the motor link
• M3x20mm (x4) : attach the casing to basis (x2) and bottom plate (x2)
• M3x30mm (x4) : attach tube to flange (x2) + attach scale to the base (x2)
• M5x30mm (x4) : attach flange to casing
• M5x40mm (x2) : attach the tank to the tube
• M5x75mm (x2) : attach Kombiblock to the base
• 2 wood screw 3x25mm to screw the "Schüsselring_klein" to the scale
• glue the "Schüsselring_groß" to the bowl

• 18/06/24:

  • Added button to make the sensor tare from HA. Clean the bowl and click on the button to reset the zero. Warning: mandatory to have made the first calibration manually, and set the "inital_zero" global value correctly
  • Added YAML of my HA cards
  • Fixed mistakes on wiring diagram

• 28/06/24:

  • Added button in HA for manual feeding cycle
  • Added a tare before distribution. Why ?
  • Before: feeder would only complete the quantity to reach expected level (example : 6g in the bowl, feeder only add 14g to reach 20g => cat is sad)
  • Now: feeder add expected quantiy to existing one (example : 6g in the bowl, set to 0g, feeder add 20g, reset tare so sensor show real value of 26g => cat is happy)
• 05/01/25
  • Added remix of casing to implement button + led for autonomous working (no HA needed)
  • Yaml modified to add the button + led and implement webserver v3 for those without HA
  • Yaml modified with slider to setup the weight to be dispensed and the max count before tank is empty
  • Added screw list
